NAME         top

       wcscspn - search a wide-character string for any of a set of wide
       characters

SYNOPSIS         top

       #include <wchar.h>

       size_t wcscspn(const wchar_t *wcs, const wchar_t *reject);

DESCRIPTION         top

       The wcscspn() function is the wide-character equivalent of the
       strcspn(3) function.  It determines the length of the longest
       initial segment of wcs which consists entirely of wide-characters
       not listed in reject.  In other words, it searches for the first
       occurrence in the wide-character string wcs of any of the
       characters in the wide-character string reject.

RETURN VALUE         top

       The wcscspn() function returns the number of wide characters in
       the longest initial segment of wcs which consists entirely of
       wide-characters not listed in reject.  In other words, it returns
       the position of the first occurrence in the wide-character string
       wcs of any of the characters in the wide-character string reject,
       or wcslen(wcs) if there is none.
